Installation
Choose the placement of the thermostats early in the construction process to enable
proper wiring during rough-in.
Consider the following:
Interior Wall.
Keep dry. Avoid potential leakage onto the control.
Relative Humidity less than 90%. Non-condensing environment.
No exposure to extreme temperatures beyond 32-122°F (0-50°C).
No draft, direct sun, or other cause for inaccurate temperature readings.
Away from equipment, appliances, or other sources of electrical interference.
Easy access for wiring, viewing, and adjusting the display screen.
Approximately 5 feet (1.5 m) off the finished floor.
The maximum length of wire is 500 feet (150 m).
Strip wire to 3/8” (10 mm) for all terminal connections.
Use standard 8 conductor, 18 AWG wire.

Caution
Improper installation and operation of this control could result in damage to the equipment
and possibly even personal injury or death. It is your responsibility to ensure that this
control is safely installed according to all applicable codes and standards. This electronic
control is not intended for use as a primary limit control. Other controls that are intended
and certified as safety limits must be placed into the control circuit.
Removing The Thermostat Base
To remove the thermostat base:
Locate the tab on the bottom of the
thermostat.
Push the tab with either your thumb or with
a screwdriver.
Lift the thermostat front away from the
thermostat’s base.

Thermostat Wiring
The thermostat can be wired in three different ways.
Stand Alone - Similar to tekmarNet
®
4 wiring with tN4 wiring terminal not used. First
stage heating relay (Rh - W1) can be wired directly to switching relays.
tekmarNet®4- Allows the thermostat to be wired using 4 wires to a tN4 Wiring Center
or Zone Manager. The tN4 communication bus can also be daisy-chained to allow
multiple thermostats to be connected together without home running wires back to the
mechanical room.
tekmarNet®2- Allows the thermostat to be wired point-to-point using 2 wires to a tN2
Wiring Center, House Control, or Zone Manager. This allows easy wiring for retrofit
applications.
Application specific wiring diagrams are provided in the 553_A brochure.
Wall
Stud
Thermostat
Front
Thermostat
Base
If a gang box is not used:
Feed the wiring through the
large hole in the thermostat
base.
Mount the thermostat base
directly to the wall.
Use screws in the screw
holes to fasten the
thermostat to the wall. At
least one of the screws
should enter a wall stud or
similar rigid material.
Terminate wiring to the
wiring strip.
Push the thermostat front
onto the thermostat base.

Testing tekmarNet®2 Wiring
------------------------------------------
------------------------------------------
Testing the Power
If the thermostat display turns on, this indicates that the thermostat is operating
correctly and there are no electrical issues. In the event that the display is off, or the
display is cycling on and off:
1. Remove the thermostat wiring cover.
2. Check to ensure that the tN2 wires on the thermostat are connected to a zone on a
House Control, Wiring Center, or Zone Manager.
3. Use an electrical meter to measure DC voltage between the tN2 terminals.
If the DC voltage is 0 V (dc) for at least 20 seconds, then there is an open or
short circuit in the tN2 wires.
If the DC voltage is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5
seconds, this indicates the wiring is correct.
4. If the thermostat display is off, or is cycling on and off, move the thermostat to the
next available zone on the House Control, Wiring Center, or Zone Manager.
If the thermostat display remains permanently on, there may be a fault with the
previously tried zone on the House Control, Wiring Center, or Zone Manager.
If the thermostat display continues to be off, or is cycling on and off, there may
be a fault on the thermostat.
If a fault is suspected, contact your tekmar sales representative for assistance.
Testing tekmarNet®4 and Stand Alone Wiring
--------------------------
--------------------------
Testing the Power
1. Remove the front cover from the thermostat.
2. Use an electrical test meter to measure (ac) voltage between the R and C terminals.
The reading should be 24 V (ac) +/– 10%.
3. Install the front cover.
Testing the Relay Outputs
--------------------------------------------
--------------------------------------------
The thermostat includes a User Test to check if the thermostat’s relays are operating
and that the thermostat is wired correctly to the HVAC equipment. The User Test setting
can be located in the Toolbox menu. Either Heat or Cool test can be selected.
Cancel button - Exits the user test and returns the Toolbox menu.
Hold button - Pauses the user test step for up to 5 minutes.
Next Item button - Advances the user test to the next test step.
